Are the nation's ports adequate for our present and future needs? This volume points out that no significant new deep-water construction has occurred for a decade, and provides the information and analysis needed to goad the ports and the federal government into action. The book asks three questions: Is additional port construction and maintenance dredging needed now or over the next 20 years? What would prevent dredging if it is needed? What alternatives could make additional dredging possible? The book identifies several problems in dredging ports, including the long interval between a decision to deepen a port and the time the alterations are complete. The United States needs to speed port construction to meet changing needs, and the committee recommends that we prepare for future needs by dredging now.

The varied use of dredgers has led to the development of a variety of dredger types, from small ones appropriate to modest inshore projects, to very large sea-going dredgers for large-scale projects calling for the storage of dredged material within the ship. This book, which is the first book dedicated to dredging and its environmental impact in the widest sense, contains chapters on dredging operations in the Netherlands, Belgium, the UK, Spain, the US, China and Singapore. Additional chapters discuss more general aspects such as dredging techniques, monitoring of dredging operations, and the prospects of dredging in a changing environment. As well as providing information on dredging activities in different areas, it gives an insight into the activities and problems (environmental or other) involved in modern dredging. It will be of interest to professionals and students alike.

L'accès des navires aux zones portuaires est assuré par le dragage de quantités importantes de sédiments. Les matériaux dragués ne peuvent être immergés que s'ils présentent toutes les garanties d'innocuité pour le milieu marin. Après un rappel sur la géochimie et la toxicité des différents contaminants qui sont adsorbés sur les sédiments, le présent ouvrage propose une approche globale de l'évaluation des risques environnementaux liés aux immersions. Les méthodes de caractérisation des risques à partir de l'analyse chimique (Géodrisk) et de tests de toxicité sélectionnés, de bioévaluation de la qualité des sédiments par la définition d'un Indice d'évaluation de l'endofaune côtière (I2EC) et de biomonitoring actif des zones d'immersion, sont décrites de manière détaillée. Cette démarche ascendante et itérative, appliquée au contexte réglementaire français, permet de satisfaire aux recommandations des conventions internationales et en particulier aux lignes directrices OSPAR.
